OZONE ALERT FOR CT: Unhealthy air quality expected Friday for certain groups

An unhealthy air quality is being predicted for “sensitive groups” in northern Fairfield County on Friday, May 8.

The state Department of Energy and Environmental Protection (DEEP) made the forecast based on predicted elevated ground-level ozone pollution for parts of Connecticut. This includes northern Fairfield, northern New Haven, Litchfield, Hartford and Tolland counties.

A forecast of “Unhealthy for Sensitive Groups” indicates increased likelihood of respiratory symptoms and breathing discomfort in active children and adults with respiratory disease, such as asthma, as well as the elderly.

Serious health risks

Ground level or "bad" ozone primarily occurs during very warm summer days. Strong sunshine causes chemical reactions of air pollutants emitted from motor vehicles, power plants and industry and household activities, forming ozone.

Warmer weather can bring high levels of ground level ozone (O3) and fine particulate matter (PM2.5). These two air pollutants pose serious health risks to “sensitive groups.”

The DEEP monitors, tracks and forecasts daily air quality levels across Connecticut for ozone from May 1 through Sept. 30, and for fine particulate matter each day of the year.
